FIELD OF THE INVENTION

The present invention generally relates to solid pharmaceutical compositions of MRTX1133 (4-(4-((1R,5S)-3,8-diazabicyclo[3.2.1]octan-3-yl)-8-fluoro-2-(((2R,7aS)-2-fluorohexahydro-1Hpyrrolizin-7a-yl)methoxy)pyrido[4,3-d]pyrimidin-7-yl)-5-ethynyl-6-fluoronaphthalen-2-ol); methods for preparing these compositions, and methods of their use for the treatment of various diseases and disorders.

BACKGROUND OF THE INVENTION

Kirsten Rat Sarcoma 2 Viral Oncogene Homolog (“KRas”) is a small GTPase and a member of the Ras family of oncogenes. KRas serves as a molecular switch cycling between inactive (GDP-bound) and active (GTP-bound) states to transduce upstream cellular signals received from multiple tyrosine kinases to downstream effectors regulating a wide variety of processes, including cellular proliferation (e.g., see Alamgeer et al., (2013) Current Opin Pharmcol. 13:394-401).

The role of activated KRas in malignancy was observed over thirty years ago (e.g., see Santos et al., (1984) Science 223:661-664). Aberrant expression of KRas accounts for up to 20% of all cancers and oncogenic KRas mutations that stabilize GTP binding and lead to constitutive activation of KRas and downstream signaling have been reported in 25-30% of lung adenocarcinomas. (e.g., see Samatar and Poulikakos (2014) Nat Rev Drug Disc 13(12): 928-942 doi: 10.1038/nrd428). Single nucleotide substitutions that result in missense mutations at codons 12 and 13 of the KRas primary amino acid sequence comprise approximately 40% of these KRas driver mutations in lung adenocarcinoma. KRAS G12D mutation is present in 25.0% of all pancreatic ductal adenocarcinoma patients, 13.3% of all colorectal carcinoma patients, 10.1% of all rectal carcinoma patients, 4.1% of all non-small cell lung carcinoma patients and 1.7% of all small cell lung carcinoma patients (e.g., see The AACR Project GENIE Consortium, (2017) Cancer Discovery; 7(8):818-831. Dataset Version 4).

The well-known role of KRas in malignancy and the discovery of these frequent mutations in KRas in various tumor types made KRas a highly attractable target of the pharmaceutical industry for cancer therapy.

Compounds that inhibit KRas activity are still highly desirable and under investigation, including those that disrupt effectors such as guanine nucleotide exchange factors (e.g., see Sun et al., (2012) Agnew Chem Int Ed Engl. 51(25):6140-6143 doi: 10.1002/anie201201358) as well recent advances in the covalent targeting of an allosteric pocket of KRas G12C (e.g., see Ostrem et al., (2013) Nature 503:548-551 and Fell et al., (2018) ACS Med. Chem. Lett. 9:1230-1234). Clearly, there remains a continued interest and effort to develop inhibitors of KRas, particularly inhibitors of activating KRas mutants, especially KRas G12D.

A noncovalent inhibitor of KRas G12D is MRTX1133 (4-(4-((1R,5S)-3,8-diazabicyclo[3.2.1]octan-3-yl)-8-fluoro-2-(((2R,7aS)-2-fluorohexahydro-1Hpyrrolizin-7a-yl)methoxy)pyrido[4,3-d]pyrimidin-7-yl)-5-ethynyl-6-fluoronaphthalen-2-ol). An amorphous form of this compound was described in International Patent Application PCT/US2020/048194 filed Aug. 27, 2020 and published as WIPO publication WO2021/041671 on Mar. 4, 2021 at Example 252. The compound is also described in Qinheng Zheng et al, Identification of MRTX1133, a Noncovalent, Potent, and Selective KRASG12D Inhibitor, J. Med. Chem, 2022, 65, 4, 3123-3133.

A need therefore exists for a pharmaceutical composition of MRTX1133 which displays suitable bioavailability and shelf-life stability, which is not susceptible to liquid capsule leakage over time, and which has fewer side effects compared with capsule formulations.

The term “MRTX1133” as used herein refers to a compound with the following formula:

as well as pharmaceutically acceptable salts of this compound. The compound has the following chemical name: (4-(4-((1R,5S)-3,8-diazabicyclo[3.2.1]octan-3-yl)-8-fluoro-2-(((2R,7aS)-2-fluorohexahydro-1Hpyrrolizin-7a-yl)methoxy)pyrido[4,3-d]pyrimidin-7-yl)-5-ethynyl-6-fluoronaphthalen-2-ol). The invention encompasses amorphous and crystalline forms of MRTX1133. An amorphous form of this compound was described in International Patent Application PCT/US2020/048194 filed Aug. 27, 2020 and published as WIPO publication WO2021/041671 on Mar. 4, 2021 at Example 252. The compound is also described in Qinheng Zheng et al, Identification of MRTX1133, a Noncovalent, Potent, and Selective KRASG12D Inhibitor, J. Med. Chem, 2022, 65, 4, 3123-3133. The contents of this patent application and of the literature reference are hereby incorporated by reference in their entirety.

As used herein, “KRas G12D” refers to a mutant form of a mammalian KRas protein that contains an amino acid substitution of an aspartic acid for a glycine at amino acid position 12. The assignment of amino acid codon and residue positions for human KRas is based on the amino acid sequence identified by UniProtKB/Swiss-Prot P01116: Variant p.Glyl2Asp.

The term “composition” as used herein is intended to encompass a product comprising the specified ingredients (and in the specified amounts, if indicated), as well as any product which results, directly or indirectly, from combination of the specified ingredients in the specified amounts. By “pharmaceutically acceptable” it is meant the diluent, excipient or carrier must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.

The term “solid composition” as used herein is intended to encompass capsules (including but not limited to gelatinous capsules containing viscous solution), tablets, powders, and other non-liquid formulations.

The neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of the present invention.

The term “crystalline” and related terms used herein, when used to describe a substance, component or product, means that the substance, component or product is crystalline as determined by X-ray diffraction. See, for example, Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing, Easton PA, p. 173 (1990); The United States Pharmacopeia, 23rd ed., pp. 1843-1844 (1995); the contents of which are hereby incorporated by reference in their entireties.

The term “pharmaceutically acceptable salts” is meant to include salts of active compounds which are prepared with relatively nontoxic acids. Acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic; propionic; isobutyric; maleic; malonic; benzoic; succinic; suberic; fumaric; mandelic; phthalic; benzenesulfonic; toluenesulfonic, including p-toluenesulfonic, m-toluenesulfonic, and o-toluenesulfonic; citric; tartaric; methanesulfonic; and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge et al. J. Pharm. Sci. 66:1-19 (1977)).

The term, “amorphous form,” as used herein, refers to a noncrystalline form of a substance.

The terms, “polymorphs” and “polymorphic forms” and related terms herein refer to crystal forms of a molecule. Different polymorphs may have different physical properties such as, for example, melting temperatures, heats of fusion, solubilities, dissolution rates and/or vibrational spectra as a result of the arrangement or conformation of the molecules in the crystal lattice. The differences in physical properties exhibited by polymorphs affect pharmaceutical parameters such as storage stability, compressibility and density (important in formulation and product manufacturing), and dissolution rates (an important factor in bioavailability). Polymorphs of a molecule can be obtained by a number of methods, as known in the art. Such methods include, but are not limited to, melt recrystallization, melt cooling, solvent recrystallization, desolvation, rapid evaporation, rapid cooling, slow cooling, vapor diffusion and sublimation.

Techniques for characterizing polymorphs include, but are not limited to, differential scanning calorimetry (DSC), X-ray powder diffractometry (XRPD), single crystal X-ray diffractometry, vibrational spectroscopy, e.g., IR and Raman spectroscopy, solid state NMR, hot stage optical microscopy, scanning electron microscopy (SEM), electron crystallography and quantitative analysis, particle size analysis (PSA), surface area analysis, solubility studies and dissolution studies.

The term, “solvate,” as used herein, refers to a crystal form of a substance which contains solvent. The term “hydrate” refers to a solvate wherein the solvent is water.

The term, “desolvated solvate,” as used herein, refers to a crystal form of a substance which can only be made by removing the solvent from a solvate.

The term “excipient” refers to an inactive ingredient of the pharmaceutical compositions of the invention. It includes, but is not limited to, solvents, wetting agents, diluents, superdisintegrants, binders, glidants, and lubricants.

The terms “treat”, “treating” or “treatment”, as used herein, refer to the reduction or amelioration of the progression, severity, and/or duration of a disorder or the eradication, reduction or amelioration of symptoms of a disorder, or the delay of the recurrence or onset of a disorder or one or more symptoms thereof in a subject that results from the administration of one or more compound.

As used herein, treatment means any manner in which the symptoms or pathology of a condition, disorder or disease are ameliorated or otherwise beneficially altered. Treatment also encompasses any pharmaceutical use of the compositions herein.

As used herein, amelioration of the symptoms of a particular disorder by administration of a particular pharmaceutical composition refers to any lessening, whether permanent or temporary, lasting or transient that can be attributed to or associated with administration of the composition.

As used herein, the term “subject,” “individual,” or “patient,” used interchangeably, refers to any animal, including mammals such as mice, rats, other rodents, rabbits, dogs, cats, swine, cattle, sheep, horses, primates, and humans. In some embodiments, the patient is a human. In some embodiments, the subject has experienced and/or exhibited at least one symptom of the disease or disorder to be treated and/or prevented. In some embodiments, the subject has been identified or diagnosed as having a cancer having a KRas G12D mutation (e.g., as determined using a regulatory agency-approved, e.g., FDA-approved, assay or kit). In some embodiments, the subject has a tumor that is positive for a KRas G12D mutation (e.g., as determined using a regulatory agency-approved assay or kit). The subject can be a subject with a tumor(s) that is positive for a KRas G12D mutation (e.g., identified as positive using a regulatory agency-approved, e.g., FDA-approved, assay or kit). The subject can be a subject whose tumors have a KRas G12D mutation (e.g., where the tumor is identified as such using a regulatory agency-approved, e.g., FDA-approved, kit or assay). In some embodiments, the subject is suspected of having a KRas G12D gene-associated cancer. In some embodiments, the subject has a clinical record indicating that the subject has a tumor that has a KRas G12D mutation (and optionally the clinical record indicates that the subject should be treated with any of the compositions provided herein).

The term “pediatric patient” as used herein refers to a patient under the age of 16 years at the time of diagnosis or treatment. The term “pediatric” can be further divided into various subpopulations including: neonates (from birth through the first month of life); infants (1 month up to two years of age); children (two years of age up to 12 years of age); and adolescents (12 years of age through 21 years of age (up to, but not including, the twenty-second birthday)). Berhman R E, Kliegman R, Arvin A M, Nelson W E. Nelson Textbook of Pediatrics, 15th Ed. Philadelphia: W.B. Saunders Company, 1996; Rudolph A M, et al. Rudolph's Pediatrics, 21st Ed. New York: McGraw-Hill, 2002; and Avery M D, First L R. Pediatric Medicine, 2nd Ed. Baltimore: Williams & Wilkins; 1994.

Example 2: Pharmacokinetics in Dogs

Test System and Study Design

Three, non-naïve, fasted and pentagastrin-pretreated (IM injection, 6 μg/kg, 30 mins prior to each administration), male beagle dogs (≥8 kg and ≥6 months old) were administered 3 (three) 150 mg MRTX1133 (00 size) capsules, administered at T=0, 12, 24, 36 hours for a total of 6 capsules per day.

Blood Samples were Collected on:

    • T=0, 0.25, 0.5, 1, 2, 4, 8, 12, 13, 14, 15, 18, 24, 25, 26, 27, 30, 36, 37, 38, 39, 42 and 48 h.

Blood was collected into commercially available tubes (Jiangsu Kangjian Medical Supplies co., LTD) containing Potassium (K2) EDTA (0.85-1.15 mg) gently inverted several times to ensure mixing and placed on wet ice until processed for plasma. Samples were centrifuged (3,200×g for 10 minutes at 2 to 8° C.) within 30 minutes from collection. The plasma sample (2*100 μL, one for analysis, one for backup) were transferred into labeled polypropylene micro-centrifuge tubes and stored frozen in a ≤−60° C. freezer until analyzed.

Test articles concentrations (ng/mL) in plasma were quantified by LC-MS/MS with internal standard.

Pharmacokinetic studies in beagle dogs were designed to administer 450 mg dose twice daily for two days. From the results of the study, it is evident that the first 24 hours of administration, blood levels demonstrated the need for MRTX1133 equilibration; thus, only the second 24 hours are taken into consideration to assess success.

The pharmacokinetic profiles of the tested formulations are shown in FIG. 1. The X-axis is time (hours) and the Y-axis is blood concentration (ng/mL). The main measure of success of each formulation is the ability to deliver MRTX1133 in blood at levels above 100 ng/mL during the 12 hours post-administration time interval. Based on the data illustrated in FIG. 1, formulations MRTA191, MRTA193, MRTA194, MRTA195, MRTA197 show rather similar pharmacokinetic characteristics, delivering 100 ng/mL MRTX1133 for the majority of time post dosage administration. Formulation MRTA196, does not contain SAIB and absorption above the 100 ng/mL in Beagle dogs was not as desirable as formulations MRTA191, MRTA193, MRTA194, MRTA195 and MRTA197. Although for MRTA196 for short periods, 100 ng/mL blood concentration is reached, the majority of post administration time, blood concentration remains below the desirable level.

Based on the pharmacokinetic data presented in this study, it was surprisingly found that SAIB plays an important role in the absorption of MRTX1133 in comparison with all other ingredients used.

Table 3 lists pharmacokinetic data of MRTA191 formulation. FIG. 2 is a graph of plasma concentration of MRTX1133 after MRTA191 dosing.

Example 3: Pharmacokinetics in Humans

The pharmacokinetics [PK] of the MRTX1133 formulation after oral administration has been evaluated in 25 subjects across 3 escalating dose frequencies under fasting conditions (200 mg twice daily [BID], 400 mg BID, and 800 mg BID), as well as evaluation of 400 mg BID when administered with a low-fat meal (i.e., under fed conditions). The mean (+standard deviation) single-dose and multiple-dose pharmacokinetic profiles of the evaluated doses are presented in FIG. 9 and FIG. 10, respectively. Individual single- and multiple-dose PK profiles can be found in FIG. 11. For all figures, the X-axis represents nominal time of sample collection (hours [h]) and the Y-axis represents plasma concentration (ng/mL). Table 10 lists PK data following the oral administration of a single dose and multiple doses of MRTX1133 formulation by dose level and subject.

When the MRTX1133 dose was increased from 200 mg BID to 400 mg BID under fasted conditions, it resulted in an increase in the mean exposure, approximately 1.8-fold following a single dose and 4.4-fold following multiple doses. However, the mean single- and multiple-dose exposure did not change in a clinically meaningful manner when the dose was increased from 400 mg BID to 800 mg BID under fasted conditions, when accounting for the high degree of inter-patient variability.

The administration of a low-fat meal with 400 mg BID did not result in a clinically meaningful change in exposure compared to administration under fasted conditions.

Overall, the MRTX1133 formulation exhibited very high inter-patient variability across all dose levels, with the % CV ranging from approximately 65 to 200%. A select number of patients receiving MRTX1133 formulation (200 mg BID fasted: 0/5, 400 mg BID fasted: 3/7, 400 mg BID fed: 1/5, 800 mg BID fasted: 3/8) were able to achieve the target human efficacious exposure derived from mouse xenograft models (>40 to 60 ng/mL for ≥8 h of a 12 h dosing interval), following administration of multiple oral doses.
